LONG BEACH, Calif. – The first openly gay member of Congress said Sunday it was a mistake for President-elect Barack Obama to invite evangelical pastor Rick Warren to deliver the invocation at his inauguration.

“Mr. Warren compared same-sex couples to incest. I found that deeply offensive and unfair,” Rep. Barney Frank, a Massachusetts Democrat, said in a broadcast interview.

“If he was inviting the Rev. Warren to participate in a forum and to make a speech, that would be a good thing,” Frank said. “But being singled out to give the prayer at the inauguration is a high honor. It has traditionally given as a mark of great respect. And, yes, I think it was wrong to single him out for this mark of respect.”

Under fire for opposing gay marriage, influential evangelical pastor Warren said Saturday that he loves Muslims, people of other religions, Republicans and Democrats, and he also loves “gays and straights.”

Says it’s OK to disagree
The 54-year-old pastor and founder of Saddleback Church in Southern California told the crowd of 500 that it’s unrealistic to expect everyone to agree on everything all the time.

“You don’t have to see eye to eye to walk hand in hand,” said Warren.

Warren also defended President-elect Barack Obama’s invitation that he give the invocation at the Jan. 20 inauguration in the keynote speech he delivered at the Muslim Public Affairs Council’s annual convention in Long Beach.

Obama’s choice of Warren earlier this week sparked outcry from gay rights and other liberal groups, who said choosing such an outspoken opponent of gay marriage was tantamount to endorsing bigotry.

“Three years ago I took enormous heat for inviting Barack Obama to my church because some of his views don’t agree (with mine),” he said. “Now he’s invited me.”

Warren said he prays for the same things for Obama that he prays for himself: integrity, humility and generosity.

Obama defends ‘wide range of view points’
Obama defended his choice on Thursday, saying that he has also invited Joseph Lowery, a Methodist minister and civil rights leader who supports same-sex marriage and gay rights, to deliver the benediction.
